Install Underdeck System Wall Trim

What happens here

Install the wall trim pieces, which act as channels to accept the underdeck panels and main rails. Measure and cut the wall trim to fit the perimeter of the underdeck system where it meets the house or any vertical structure. The wall trim must follow the same pitch established by the pitch rails, so ensure it aligns perfectly with the angle of the underdeck ceiling. Screw the wall trim securely into the house siding or structure. This creates a clean, straight edge and provides a secure attachment point for the underdeck panels.

Goal: Secure the wall trim pieces around the perimeter of the underdeck system, ensuring they follow the established pitch and are flush with the house siding.
